Support of init-exec sub package

Custom init type (#1658)

Merge remote-tracking branch 'upstream/stable' into merge_stable

also remove dead code-mirror2.dlang.io fallback

fix Issue #1522 - avoid insecure fallbacks ...

- opens dub for possible MITM attacks

improve package supplier fallback logic ...

- scope (failure) did swallow fatal errors
- improve logging of failures and successes
- rethrow failure of default registry instead of from the last one
- remove failing package suppliers, so we don't keep beating dead horses

Note that some retry logic is already done interally by package suppliers,
so a failing one is unlikely to recover on the next usage.

Add experimental feature to improve build cache efficiency

the passed string[] are sorted so assumeSorted is ok.

infer unspecified version filters ...

- otherwise of little use as all dependencies need to have specified
  version filters before this can be used
- also version identifiers are fairly easy to grep for
- cache inferred version filters
- still allows explicit specification for packages that use version
  identifiers in mixins

Fix #1478 - Quote paths passed to xcopy

Use default architecture for ddox

Fix #1478 - Quote paths passed to xcopy ...

On Windows, `cd` accepts unquoted paths, but for any calls to `xcopy`,
paths arguments must be double-quoted. This patch surrounds all paths
with double-quotes before passing them to `xcopy`.

This fixes #1478: On Wine (and presumably Windows XP), migrating the dub
package directory from dub 1.7 to dub 1.8/1.9 via `xcopy` failed an
enforce in dub (because `xcopy` quit with nonzero exit code) and thus
prevented even the most simple dub projects from being built.

D WYSIWYG strings (backtick-surrounded strings) allow all characters
unescaped, including double quotes and backslashes.

Maven upgrade dependency tree

Clean sub-packages when main package target type is "none"

Support more vars in build settings ...

fixes dlang/dub#1447

remove regular upgrade check ...

- avoids "build" failures due to connectivity issues or pending dependency conflicts
- `dub build --nodeps` now only suppresses resolution of missing dependencies
- add an explicit `dub upgrade --dry-run` to check for new packages

Add skipRegistry option to settings.json

Split-up package suppliers into individual modules

Merge pull request #1459 from dlang/issue_838_custom_cache_paths ...

Add a "customCachePaths" configuration field

remove only occurence of ctRegex

Add a "customCachePaths" configuration field. Fixes #838. ...

Allows defining additional paths that contain packages in sub folders with the pattern "(name)-(version)/(name)/" by defining a "customCachePaths" field in /etc/dub/settings.json or ~/.dub/settings.json.
